Subtracting your checklist from what I've climbed leaves a short list. But none of these are very hard, and all are about 100-120 miles away.

Whale Peak, north of 285 from Hall Valley campground, 9 miles r/t, easy class 2.Bald Mountain and Boreas Peak from Boreas Pass, accessible from the south from Como.Gray Wolf Mtn and Mt Spalding from Guanella Pass. Also Square Top Mtn.I haven't climbed it, but Lenawee Mtn from either the A-Basin parking lot or the back side from Montezuma (Peru Creek?) should work.
